"Top-Down" refers to a management or decision-making approach where directives and strategies originate from higher levels of an organization and flow down to lower levels. This method emphasizes a clear hierarchy, with leaders setting goals and expectations that subordinates are expected to follow. It is often used in corporate settings to ensure alignment and consistency across various departments. In software development, the "Top-Down" approach involves breaking down a system into smaller components, starting from the highest level of abstraction. This method allows developers to focus on the overall structure before delving into specific details, facilitating easier project management and clearer understanding of the system's functionality.
